1.0 INTRODUCTION

1.1 Project Purpose and Scope of Work

DesertXpress Enterprises, LLC (DXE) is proposing to construct and operate a dedicated 

two-tracked high speed passenger railway and associated operations and maintenance 

facilities between Victorville, California, and Las Vegas, Nevada (DesertXpress Project; 

Exhibit A, Figure 1). A Draft Environmental Impact Statement was issued for the project 

in March of 2009 and the Final EIS is nearing completion. A Supplemental Draft EIS has 

been prepared and will be issued shortly to address certain modifications to the proposed 

alignment and station locations made by the Applicant, DXE, in response to various 

comments made on the Draft. The U.S. Department of Transportation, Federal Railroad 

Administration (FRA) is the lead agency responsible for preparing the project 

Environmental Impact Statement (EIS).

In preparation for the permit phase of the project, DXE has retained Huffman-Broadway 

Group, Inc. (HBG) to investigate the presence of wetlands and other waters potentially 

subject to Corps and EPA regulation under Section 404 of the Clean Water Act (CWA) 

along the DesertXpress Project’s preferred and alternative alignments and study areas for 

the stations and ancillary facilities.

For the purpose of the jurisdictional delineation study the proposed DesertXpress Project 

has been divided into six areas using the USGS HUC 8 1 level of watershed classification.

The scope of this report is to evaluate the presence or absence of wetlands and waters 

potentially subject to Corps CWA jurisdiction within the proposed DesertXpress Project 

alignments and facilities located within the HUC 8 Mojave and Coyote - Cuddeback 

Lakes watersheds (Exhibit A, Figure 2). 

This study was conducted in accordance with Code of Federal Regulations (CFR) 

definitions of jurisdictional waters, the Corps’ 1987 Wetlands Delineation Manual, the 

Corps’ 2008 Regional Supplement to the Corps of Engineers Wetland Delineation 

Manual: Arid West Region (Version 2.0), and supporting guidance documents. The 

remaining portions of Section 1.0 provide project contact information, describe the 

location of the Study Area and provide technical details regarding the general 

environmental conditions found within the Study Area, including relevant technical 

information from the Draft EIS regarding water resource data and biological and cultural 

resource information. Section 2.0 provides regulatory background information and 

details regarding the technical criteria and types of field indicators evaluated for during 

1 HUC = U.S. Geological Survey (USGS) Hydrologic Unit Code. The Hydrologic Unit system is a standardized 

watershed classification system developed by USGS in the mid 1970s. Hydrologic units are watershed boundaries 

organized in a nested hierarchy by size. They range in size from national regions, to the smaller cataloging units 

(HUCs), which are roughly equivalent to local watershed.

the study. Section 3.0 provides a detailed description of the methods used during this 

investigation. Section 4.0 provides a description of technical findings and Section 5.0 

describes the types of areas found that potentially may be subject to Corps CWA 

jurisdiction. Section 6.0 is a Clean Water Act jurisdictional analysis using the Rapanos 

Guidance.

HBG is seeking, on behalf of DXE, a Preliminary Jurisdictional Determination pursuant 

to applicable Corps guidance documents.

1.3 Study Area

The Study Area for this investigation is defined as the area where potential ground 

disturbing components of the proposed project would occur based on the alternatives 

identified and analyzed in conjunction with the EIS and Supplemental EIS prepared for 

the DesertXpress Project. The Study Area extends approximately 105 miles eastward 

from the proposed Victorville station to the Halloran Summit east of the town of Baker 

(Exhibit A, Figure 3). 

1.4 Environmental Setting 

The Study Area encompasses those portions of the proposed DesertXpress Project 

alignments and facilities between Victorville, California, and Las Vegas, Nevada, that lie 

within the Mojave Watershed (HUC-8 18090208) in San Bernardino County. The 

alignment alternatives pass through, from west to east, the following HUC-12 

watersheds: 

 Bell Mountain Wash

 Brisbane Valley-Wild Wash

 Town of Lenwood-Mojave 

River

 Town of Johnstons Corner

 180902081004

 City of Barstow- Mojave River

 Odessa Canyon

 Sunrise Canyon-Mojave River

 Lake Jodie-Mojave River

 Dolores Lake 

 Manix Wash 

 Wilhelm Wash-Mojave River

 Afton Canyon-Mojave River 

 West Cronise Lake

 East Cronise Lake

 180902082502

 180902082504

 Oasis of Mara-Soda Lake 

 Otto Mountain-Silver Lake

 Hytens Well

 Halloran Spring-Halloran 

Wash

F-I.6-6
Figure 4 in Exhibit A shows the boundaries of these HUC 12 watersheds. All the above 

HUC-12 watersheds are within the Mojave Watershed (HUC-8) exception for Dolores 

Lake: I-15 straddles the boundary between the Dolores Lake watershed, which lies within 

the Coyote-Cuddeback Lakes HUC-8 watershed, and the Lake Jodie-Mojave River HUC12 watershed. 

The Study Area includes segments of the proposed alignment alternatives and facilities 

described in the Draft and Supplemental Environmental Impact Statement as Segments 1 

and 2 and part of Segment 3 Alternative 3B. Segment 1 is the portion of the alignment 

from Victorville through Barstow. Segment 2 extends from the east side of Barstow 

through Yermo. The part of Segment 3 Alternative 3B that is within the Mojave 

Watershed is the portion of the alignment from Yermo eastward through Baker to 

Halloran Summit (see Figure 1 in Exhibit A). The DesertXpress route through the 

Mojave Watershed generally follows the I-15 right of way. 

The principal hydrologic feature in the study area is the Mojave River. From its 

headwaters in the San Bernardino Mountains, the Mojave River, via both surface and 

subsurface flow, crosses the watershed for approximately 120 miles before terminating at 

Silver Dry Lake near Baker (or Soda Lake, in drier years). Aside from intense storm 

events, the Mojave River channel is typically dry downstream of the Mojave Forks Dam 

east of Hesperia (about 18 miles south of Victorville) except where groundwater is forced 

to the surface by geologic structures. 

1.4.1 Topography

The Study Area is within the Mojave Desert Geomorphic Province. The Mojave Desert 

Geomorphic Province is characterized by mountain ranges and hills of moderate relief 

that are partially buried and separated by broad alluviated basins. . 

The DesertXpress Project alternatives and facilities through the Study Area begins at an 

approximate elevation of 3,000 feet msl in Victorville, before descending to Barstow at 

about 2,100 feet msl. From Barstow, the alignment extends through the Mojave River 

Valley, Cronise Valley, the Soda Mountains and Soda Lake to Baker at an elevation of 

about 920 feet msl, then climbs the Halloran Springs Valley to Halloran Summit at an 

elevation of approximately 4,100 feet msl. 

1.4.2 Land Use

Except for an approximately 8-mile diversion near Yermo east of Barstow, the proposed 

DesertXpress Project alignment alternatives through the Mojave Watershed is in the I-15 

right of way on the north side of the freeway. In much of the Study area, the 

DesertXpress Project preferred alignment is within the interstate I-15 right of way / 

transportation corridor. It extends from the station north of Victorville through the towns 

of Lenwood (a Barstow suburb), Barstow, Yermo, and Baker, primarily on the north side 

of I-15 to Halloran Summit.

1.4.3 Geology and Soils

This section taken from the Draft EIS describes the geology within each segment of the 

Study Area. Tables list the geologic unit type and the age and description of geologic 

units mapped within each segment. 

Segment 1 – Victorville through Barstow

Segment 1 is underlain by both alluvial sediments and older Mesozoic age granitic, 

volcanic, and metavolcanic rocks. The alluvial deposits include younger Holocene wash 

sediments (Qw) and valley sediments (Q, Qa), older Pleistocene valley and fan sediments 

(Qo, Qoa, Qod), and alluvial fanglomerate deposits (Qof). Underlying these alluvial 

sediments at a relatively shallow depth (and exposed in some places) are granitic quartz 

monzonite, hornblende diorite-gabbro and granite (KJqm, Qm, Gqm, Hd) and porphyritic 

metavolcanic rock (Mzv, Lp, Pf). 

Geologic Unit (Symbol[s]) Geologic Age Description - Soils

Younger alluvial valley sediments (Q, Qa) Holocene Unconsolidated, poorly sorted alluvial silt, 

sand and gravel 

Younger alluvial river/wash deposits (Qw ) Holocene Alluvial wash deposits.

Older alluvial valley and fan sediments (Qo,

sand, and silt derived mainly from granitic and 

metamorphic rocks of San Gabriel /San 

Bernardino Mtns.

Older alluvial fanglomerate (Qof) Pleistocene Cobble fanglomerate and gravel derived from 

metavolcanic rocks.

Porphyritic volcanic and metavolcanic rocks. 

Includes Sidewinder Volcanic Series (Bowen, 

1954), and Oro Grande (Hershey, 1902)

Source: Ninyo & Moore, 2007.

Segment 2 – East of Barstow through Yermo 

Segment 2 Alternative 2C is on the north side of I-15 near but not within the freeway 

right of way. Three geologic units that underlie the westernmost portion of this: 1) 

Mojave River sediments along the southeast and north banks of the river, 2) an exposure 

of sedimentary and volcanic rocks east of Barstow, and 3) valley alluvium sediments in 

the small drainage valley west of Yermo.

Just east of Barstow, Segment 2 would cross an area of exposed Tertiary age, volcanic 

and sedimentary rocks (Mc, Mi, Tt, Tat, Tls, Td, Ts, Tsl). In the small drainage valley 

east of this rock exposure, Segment 2 crosses alluvial deposits consisting of young fan 

and valley sediments (Q, Qa), and a clay unit deposited from a playa or small lake bed 

(Qc, Ql). Northeast of Yermo, soils are underlain by older alluvium (Qo, Qoa) and fan 

gravel (Qf) on the southeast flank of the Calico Mountains. This older alluvium and fan 

gravel mantles the formational Tertiary volcanic and sedimentary rock that comprises the 

F-I.6-8
Calico Mountains.

Source: Ninyo & Moore, 2007. 

Segment 3 Alternative 3B– Yermo to Halloran Summit 

Yermo to Baker: Southwest of Manix, soils are underlain primarily by younger alluvial 

valley and fan sediments (Q, Qa, Qal, Qf), and partially by older fanglomerate and gravel 

alluvium in (Qof, QT). Northeast of Manix, soils are underlain by Manix Lake sand and 

silt sediments (Qms, Qol), younger river sand (Qrs, Qw) from tributary channels of the 

Mojave River, and by an area of older alluvium. Further northeast, the alignment 

continues through the Mojave River Valley and is underlain by younger valley alluvial 

sediments (Qal) and lacustrine (lake) deposits (Ql).

At the northeast end of the river valley, soils are underlain by older Pliocene-Pleistocene 

sediments of varying composition (Qc, QP). To the east, on the south side of the Cronise 

Mountains, soils are primarily underlain by younger alluvial sediments (Qal) and partially 

by exposures of Tertiary-Mesozoic age granitic rocks (gr, gr-m, TKq). A concealed, 

potentially active, unnamed fault is located skew to the alignment in the Cronise Valley.

In the Soda Mountains area between the Cronise Valley and Baker, soils are underlain by 

younger valley and alluvial fan deposits (Qal), older Pliocene-Pleistocene sediments of 

varying composition (Qc, QP), and by Tertiary age volcanic and sedimentary rocks (Tv, 

Tc). Exposures of Tertiary-Mesozoic age granitic rocks (gr, TKq) are found on the 

southeast side of the proposed alignment. The geologic maps indicate that Segment 3

Alternative 3B crosses the potentially active Baker fault on the east side of the Soda 

Mountains approximately 6 miles southwest of Baker. In Baker, the segment is underlain 

by younger lacustrine Soda Lake Bed sediments (Ql). 

Baker–Halloran Summit: From Baker, Segment 3 Alternative 3B ascends a broad, 

sloping alluvial fan that flanks the southwest side of the Halloran Summit. Between 

Baker and Halloran Springs, the segment is underlain by younger valley and alluvial fan 

deposits (Qal). 

F-I.6-9
The Halloran Summit area is comprised of a large body of Tertiary-Mesozoic age granitic 

rock (gr, TKq) that is overlain by younger Pleistocene age volcanic basalt flows (Qpv, 

Qeb). The granitic rock body is intruded into an older, Precambrian metamorphic rock 

XQLWFRPSULVHGRIJQHLVVHSȯSȯJRQWKHZHVWVLGHRIWKH+DOORUDQ6XPPLWSegment 3

Alternative 3B is underlain by the gneissic rock and younger alluvium (Qal) on the west 

side of the summit. Younger alluvium is mapped at the Halloran Summit pass but is 

underlain at relatively shallow depth by granitic and/or volcanic rock. The inactive 

Halloran fault runs parallel to I-15 in this area.

1.4.4 Seismology

The three potentially active fault zones described below have had a dominant role in 

forming the present seismic environment of the region. The boundaries of earthquake 

fault zones are based on the presence of well-defined, active fault traces. Zone 

boundaries are typically 500 to 660 feet away from the fault traces and are positioned to 

accommodate imprecise locations of the faults and the possible existence of active 

branches. The alignment would cross only one of these fault zones, the Eastern 

California/Mojave Shear Zone.

Eastern California/Mojave Shear Zone 

The Eastern California/Mojave Shear Zone (ECMSZ) is an approximate 50-mile-wide 

zone of tectonic deformation that crosses the central Mojave Desert and is characterized 

by numerous northwest trending, right lateral, strike-slip faults roughly centered on 

Barstow. The ECMSZ is estimated to accommodate between 9 and 23 percent of the 

relative motion between the Pacific and North American tectonic plates.2 The alignment

would cross the ECMSZ in Segments 1, 2, and 3, between Helendale and Manix, 

California. Several moderate to large earthquakes have ruptured faults within this region, 

including the Mmax 7.3 Landers earthquake (6/28/1992), and the Mmax 7.1 Hector Mine 

earthquake (10/16/1999). The Landers earthquake produced an approximate 53-milelong surface rupture that averaged approximately 10 to 13 feet of slip and occurred along 

portions of the Johnson Valley, Landers, Homestead Valley, Emerson, and Camp Rock 

faults.3 These surface rupture areas occurred south of the Study Area.

On March 18, 1997, a Mmax 5.3 earthquake occurred along the Calico fault approximately 

12 miles east-northeast of Barstow. This earthquake was the last aftershock of the 

Landers earthquake of 1992 to reach Mmax 5. Although there was no surface rupture 

attributed to this earthquake, the Calico fault had exhibited some triggered slip during the 

1992 Landers event.4

San Andreas Fault Zone 

The San Andreas Fault zone has long been recognized as the dominant seismotectonic 

feature in California. The fault is located approximately 21.3 miles southwest of the 

southwest end of the alignment. Two of California’s three largest historic earthquakes 

occurred along the San Andreas: the 1906 San Francisco earthquake (approximately 400 

miles from the study area) and the 1857 Fort Tejon earthquake (the closest surface rupture 

occurred in Wrightwood, approximately 60 miles from the southwest end of the 

alignment). The San Andreas is a right lateral strike-slip fault, capable of producing 

earthquakes in excess of Mmax 7.5.

Geologists infer that the segment of the San Andreas closest to the study area is currently 

locked and is accumulating substantial amounts of strain in response to the stresses

generated by the relative movement between the Pacific and North American plates. The 

available geologic data indicate that this strain is released during infrequent major 

earthquakes (Mmax 7 to 8+ events) rather than by more frequent smaller magnitude 

earthquakes. 

Garlock Fault 

The Garlock fault is a prominent fault in southern California and crosses the northern part 

of the Mojave Desert province. The east end of the fault is approximately 20 miles northnorthwest of Segment 3 Alternative 3B. Although this fault has not produced large 

earthquakes in recorded history, geomorphic and stratigraphic evidence indicates such 

events occurred in earlier eras. A total of about 30 to 40 miles of left-lateral strike slip 

has been documented across this fault. The Garlock fault is considered capable of 

generating about a Mmax 7.5 earthquake.

1.4.6 Climate

The project is in an arid high desert region with average monthly temperatures ranging 

from the 30s to the 90s in Fahrenheit (°F). The area is characterized by short, mild 

winters and long, hot summers. Precipitation in the area is limited, which influences 

hydrology within the area. The Mojave Desert has an arid to semi-arid climate; the area 

is in the rain shadow of 5,000 to 11,000-foot high mountains west of the area. About 2/3 

of average annual precipitation occurs between November and March, when winter 

storms move east from the Pacific Ocean. Precipitation amounts are higher in the 

mountains, ranging from about 4 inches annually in lower areas, with precipitation over 

12 inches annually in the highest elevations. In the higher mountains, winter precipitation 

may occur as snow. Precipitation in the summer comes as short, intense, and localized 

thunderstorms; much of this rain is lost to evapotranspiration, particularly if the storm is a 

small one. The farther east in the Mojave, summer storms are more frequent, as they 

arrive from Arizona to the south (NPS 1999). 

The Western Regional Climate Center (2008) provides climatological data summaries for 

weather stations throughout the western United States; data for the Victorville weather

1.4.7 Hydrology

Mojave Watershed

The following is excerpted from the Lahontan Regional Water Quality Control Board 

Watershed Management Initiative (2005), online at 

http://www.swrcb.ca.gov/rwqcb6/water_issues/programs/watershed_management: 

The Mojave Watershed encompasses approximately 4,500 square miles 

and is located entirely within San Bernardino County. . . . 

The primary geographic and hydrologic feature of the watershed is the 

Mojave River. The headwaters of the Mojave River are in the San 

Bernardino Mountains, which annually receives greater than 40 inches of 

precipitation at its highest elevations. Much of the winter precipitation in 

the San Bernardino Mountains falls in the form of snow that provides 

spring recharge to the Mojave River system. Historically, the annual 

recharge from the headwaters is approximately 75,000 acre-feet. The 

Mojave River channel, through both surface and subsurface flow, transects 

the watershed a linear distance of approximately 120miles to its terminus 

at Silver Dry Lake near the Community of Baker. Aside from seasonal 

intense storm events, the Mojave River channel is typically dry 

downstream of the Mojave Forks Dam except in select locations where 

ground water is forced to the surface by geologic structures. . . . 

Typical of southwestern arid environments, the Mojave Watershed has 

limited water resources. Surface water from the headwaters in the San 

Bernardino Mountains quickly percolates into the porous sands of the 

young Mojave River alluvium. Thus, ground water is the primary source 

of water supply in most of the watershed. . . . 

Today, most of the Mojave River channel is dry downstream of Victorville 

except during flood events. Historically, some areas contained water 

surface water throughout most of the year. Former “watering holes” for the 

Mormon and Spanish Trails were located along the Mojave River, which 

F-I.6-16
were primarily located where faults or other geologic structures force 

ground water to the surface. Due to years of overdraft conditions, the 

ground water table has been lowered to a point where most areas no longer 

contain surface water.

Construction of the I-15 diverted many of the natural drainages along the 

ROW to culverts under the highway.

Segment 1 – Victorville through Barstow

Water Resources: The major hydrological resource within the project study area for 

Segment 1 is the Mojave River, which is located near the south and north ends of this 

segment. Multiple small unnamed creeks and washes that drain into the Mojave River or 

end before reaching the river. Other than the Mojave River, the Bell Mountain Wash and 

Wild Wash are the two main drainages in Segment 1.

Groundwater Resources: Segment 1 is located in both the Upper Mojave and Middle 

Mojave River Valley Groundwater Basins.5 The total surface area of the Upper Basin 

(CDWR Basin 6-42) is 413,000 acres or 645 square miles. The Upper Basin is bounded 

by the San Bernardino Mountains on the south and follows the Mojave River through 

Victorville in Apple Valley, and ends near the community of Helendale. Natural 

groundwater recharge of the basin occurs from direct precipitation, ephemeral stream 

flow, infrequent surface flow of the Mojave River, and underflow of the Mojave River. 

The general groundwater level trend in the Upper Basin is declining. Published total 

storage capacity for the basin varies. However, the California Department of Water 

Resources (CDWR) estimates that the total groundwater storage capacity is 27,839,000 

acre-feet (af).6

The Middle Mojave River Valley Groundwater Basin (CDWR 6-41) generally flows east 

starting near the town of Helendale and ends at the Waterman fault. The total surface

area of the basin is 211,000 acres or 330 square miles. Natural recharge of the basin 

occurs through precipitation, ephemeral stream flow, infrequent surface flow of the 

Mojave River, and underflow of the Mojave River. Groundwater level trends tend to 

vary with the amount of rainfall. 

Segment 2 – East of Barstow through Yermo 

Water Resources: Segment 2 includes five unnamed drainages in addition to the 

Waterman Avenue Channel, Arrowhead Channel, and North Barstow Channel. The 

Daggett Wash drains north into the Mojave River on the south side of Yermo at the north 

end of Segment 2. 

Groundwater Resources: Portions of Segment 2 are also located in the Middle Mojave

River Valley Groundwater Basin. A discussion of the character and groundwater quality 

of this groundwater basin is provided in above relative to Segment 1. Other portions of 

Segment 2 are also located in the Lower Mojave River Valley Groundwater Basin 

(CDWR Basin 6-40). The Lower Mojave River Valley Groundwater Basin surface area 

is 286,000 acres or 447 square miles. The groundwater basin underlies an elongated eastwest valley, flowing from the Waterman fault and exiting the valley to the east through 

Afton Canyon.7

Segment 3 Alternative 3B– Yermo to Halloran Summit 

The total groundwater storage capacity is estimated to be about 

9,010,000 af. 

Water Resources: Multiple unnamed drainages meander down the Calico Mountains 

near the western half of Segment 3 Alternative 3B. North of I-15 are the West and East 

Cronise Lakes and to the south is the Mojave River Wash. In the eastern portion of 

Segment 3 Alternative 3B, the major waterbodies in the vicinity are Silver Lake to the 

north and Soda Dry Lake to the south. Silver Lake and Soda Dry Lake make up the 

remnants of Lake Mojave. These lakes are small round depressions in the surface of the 

ground that tend to fill with water when it rains. There are numerous washes and ditches 

in Segment 3 Alternative 3B, including West Manix Wash, East Manix Wash, Sheep 

Ditch, Mobi Ditch, Mojave River Wash, Halloran Wash, Valley Wells Ditch, and 

Windmill Ditch,.

Groundwater Resources: The western portions of Segment 3 Alternative 3B are located 

in the Caves Canyon Valley Groundwater Basin (Basin 6-38). This basin underlies a 

portion of the Lower Mojave River Valley in central San Bernardino County. The Caves 

Canyon basin is bound by non-water-bearing rocks of the Cady Mountains on the 

southeast, the Cronise Mountains on the east, the Cave Mountains on the northeast, low 

hills on the north, and the Alvord Mountains on the northeast.8 The estimated total 

groundwater storage capacity of the basin is 4,152,000 af. 

The next groundwater basin that Segments 3 Alternative 3B travels over is the Soda Lake 

Valley Groundwater Basin (Basin 6-33). This basin underlies a northeast-trending valley 

in northeast San Bernardino County. The basin is bounded by non water-bearing rocks of 

the Marl and Kelso mountains to the east, the Bristol and Cady mountains to the south, 

and the Soda and Cave Mountains to the west. Recharge to the basin occurs primarily 

from Mojave River percolation and percolation of runoff from the alluvial fan deposits at 

the base of the surrounding mountains. Groundwater level trends have been relatively 

stable throughout the period of record. However, declining levels have been observed in 

a couple of wells, and the most fluctuation occurs in wells near the Mojave River Sink. 

The total estimated storage capacity of the basin is approximately 9,300,300 af.9

1.4.8 FEMA Flood Zones

FEMA issues Flood Insurance Rate Maps (FIRMs) to assess the potential and affect of a 

100-year storm event. At the south end of Segment 1 is the 100-year floodplain along the 

Mojave River and Bell Mountain Wash near Stoddard Wells Road. 

The 100-year floodplain generally follows the Mojave River. The north end of Segment 1 

is within one mile of the 100-year floodplain that encompasses the southwest corner of 

Lenwood along Sylvan Avenue. Although no floodplain is mapped along the river from 

Lenwood Road south to Indian Trail, a review of the FEMA FIRM maps suggests that 

this area would be within the 100-year floodplain if it were studied. There are additional 

floodplain areas within this segment south of the BNSF railroad tracks in Lenwood, west 

of the Old Highway 58 and I-15 interchange, and at the east end of the segment along the 

intermittent canal between Ghost Town Road and Yermo Road. 

Within Segment 3 Alternative 3B, the 100-year floodplain of the Mojave River is just 

east of Yermo. North of I-15 in the community of Baker is the 100-year floodplain of 

Silver Lake. South of I-15 and Baker is the 100-year floodplain for Soda Dry Lake. Soda 

Dry Lake and Silver Lake are dry most of the time, but occasionally receive stormwater 

runoff, which evaporates and/or sinks into the ground, although capillary action draws 

some of the water back to the surface. Since the water evaporates, the salts that were 

contained in the water are left behind; giving the dry lake its crusty, white surface.

Huffman-Broadway Group, Inc. has conducted a thorough historical review and site 

investigation and made a good-faith effort herein to thoroughly describe and document

2.0 REGULATORY FRAMEWORK

2.1 Definition of Wetlands and Other Waters of the U.S.

Section 404 of the Federal Clean Water Act authorizes the Corps to regulate activities 

that discharge dredged or fill material to wetlands and other waters of the United States. 

As described by EPA’s and the Corps’ regulations (40 CFR § 230.3(s) and 33 CFR § 

328.3(a), respectively), the term “waters of the United States" encompasses the following 

resources: 

(1) All waters which are currently used, or were used in the past, or may be 

susceptible to use in interstate or foreign commerce, including all waters 

which are subject to the ebb and flow of the tide; 

(2) All interstate waters including interstate wetlands; 

(3) All other waters such as intrastate lakes, rivers, streams (including 

intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie 

potholes, wet meadows, playa lakes, or natural ponds, the use, degradation 

or destruction of which could affect interstate or foreign commerce 

including any such waters: 

(i) Which are or could be used by interstate or foreign travelers for 

recreational or other purposes; or 

(ii) From which fish or shellfish are or could be taken and sold in 

interstate or foreign commerce; or 

(iii) Which are used or could be used for industrial purpose by industries 

in interstate commerce 

(4) All impoundments of waters otherwise defined as waters of the United 

States under the definition; 

(5) Tributaries of waters identified in paragraphs (a) (1) through (4) of this 

section; 

(6) The territorial seas; 

(7) Wetlands adjacent to waters (other than waters that are themselves 

wetlands) identified in paragraphs (a) (1) through (6) of this section. 

EPA and the Corps define wetlands as: 

...those areas that are inundated or saturated by surface or ground water at 

a frequency and duration sufficient to support, and that under normal 

circumstances do support, a prevalence of vegetation typically adapted for 

life in saturated soil conditions. Wetlands generally include swamps, 

marshes, bogs, and similar areas. (EPA regulations at 40 CFR § 230.3(t); 

Corps regulations at 33 CFR § 328.3(b)). 

F-I.6-20
2.2 Limits of Jurisdiction 

The following provides the regulatory definitions and criteria followed in determining the 

geographic extent of potential EPA/Corps jurisdiction as applicable to inland waters. 

The geographic limits of relevant federal jurisdiction for non-tidal waters of the U.S. are 

defined as follows at 33 CFR § 328.4(c): 

Non-Tidal Waters of the United States: The limits of jurisdiction in non-tidal 

waters: 

(1) In the absence of adjacent wetlands, the jurisdiction extends to the 

ordinary high water mark. 

(2) When adjacent wetlands are present, the jurisdiction extends beyond the 

ordinary high water mark to the limit of the adjacent wetlands. 

(3) When the water of the United States consists only of wetlands the 

jurisdiction extends to the limit of the wetland. 

The terms “adjacent” and “ordinary high water mark,” used in the above definition, are 

defined at 33 CFR § 328.3 as follows: 

The term adjacent means bordering, contiguous, or neighboring. 

Wetlands separated from other waters of the United States by man-made 

dikes or barriers, natural river berms, beach dunes and the like are 

“adjacent wetlands.” (33 CFR § 328.3(c)) 

The term ordinary high water mark means that line on the shore 

established by the fluctuations of water and indicated by physical 

characteristics such as clear, natural line impressed on the bank, shelving, 

changes in the character of soil, destruction of terrestrial vegetation, the 

presence of litter and debris, or other appropriate means that consider the 

characteristics of the surrounding areas. (33 CFR § 328.3(e)) 

A site must meet certain water, soil, and vegetation criteria to qualify as a jurisdictional 

wetland. The Corps’ 1987 Wetlands Delineation Manual and various regional 

supplements describe these criteria and the methods used to determine whether they are 

met and the geographic extent of wetland areas identified in the field. 

2.3 Identification of Ordinary High Water Marks (OHWM)

The Corps definition of Ordinary High Water Mark (OHWM) provides the criterion by 

which the OHWM line can be identified which consists of “that line on the shore 

established by fluctuations of water and indirect physical characteristics” (33 CFR § 

328.3(e)). The Corps has developed a delineation manual for the identification of 

OHWMs within the Arid West Region, entitled A Field Guide to the Identification of the 

Ordinary High Water Mark (OHWM) in the Arid West Region of the Western United 

States, A Delineation Manual (Lichvar and McColley 2008). Tables 1a and 1b, below 

provide a summarized listing from the manual of indicators associated with areas that 

become flood or ponded, but are not dominated by wetland vegetation and the duration of 

F-I.6-21
flooding, ponding and/or near surface soil saturation (LQFKHVLVQRWVXIILFLHQWWR

2.4 Wetlands Delineation Criteria

The Corps’ 1987 Wetlands Delineation Manual identifies the key diagnostic criteria for 

determining the presence of wetlands. These include: 

1. Wetland Hydrology: Inundation or saturation to the surface during the 

growing season. 

2. Hydric Soils: Soils classified as hydric or that possess characteristics 

associated with reducing soil conditions. 

3. Predominance of Wetland Vegetation: Vegetation classified as facultative, 

facultative wet, or obligate according to its tolerance of saturated (i.e., 

anaerobic) soil conditions. 

Specific criteria used to determine the presence or absence of wetland hydrology, soil, 

and vegetation conditions are described in the sections below. 

F-I.6-23
2.4.1 Wetland Hydrology

The 1987 Corps Manual states that wetland hydrology conditions occur when a “site is 

inundated either permanently or periodically at mean water depths less than or equal to 

6.6 feet, or the soil is saturated to the surface at some time during the growing season of 

the prevalent vegetation.” Whether a site meets either of these criteria is determined by 

the presence of diagnostic indicators of wetland hydrology, which include those listed in 

Table 2.

Table 2. Wetland Hydrology Indicators

(Based on 1987 Corps Manual and Corps Guidance Documents)

Primary Indicators Secondary Indicators

Watermarks Oxidized Rhizospheres Associated with 

Living Roots

Drift Lines Water-Stained Leaves

Water-Borne Sediment Deposits FAC-Neutral Test

Drainage Patterns Within Wetlands Local Soil Survey Data

A March 8, 1992 Corps memorandum entitled Clarification and Interpretation of the 

1987 Manual provides further clarification: 

Areas which are seasonally inundated and/or saturated to the surface for a 

consecutive number of days for more than 12.5 percent of the growing 

season are wetlands, provided the soil and vegetation parameters are met. 

Areas wet between 5 percent and 12.5 percent of the growing season in 

most years may or may not be wetlands. Sites saturated to the surface for 

less than 5 percent of the growing season are non-wetlands.

Wetland hydrology indicators have also been further defined and described in the 

Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West 

Region (Version 2.0) (Corps 2008). These indicators are similar to the indicators listed 

above from the 1987 Corps Manual and are presented in Table 3.

2.4.2 Hydric Soils

The 1987 Corps Manual states that the diagnostic environmental characteristics indicative

of wetland soil conditions are met when "soils are present and have been classified as 

hydric, or they possess characteristics that are associated with reducing soil conditions." 

According to the Manual, indicators of soils developed under reducing conditions may 

include: 

1. Organic soils (Histosols); 

2. Histic epipedons; 

3. Sulfidic material;

4. Aquic or peraquic moisture regime; 

5. Reducing soil conditions; 

6. Soil colors (chroma of 2 or less); 

7. Soil appearing on hydric soils list; and 

8. Iron and manganese concretions. 

A February 20, 1992, Corps memorandum entitled Regional Interpretation of the 1987 

Manual states that the most recent version of National Technical Committee for Hydric

Soils (NTCHS) hydric soil criteria will be used (to make hydric soil determinations). 

These soil criteria specify at least 15 consecutive days of saturation or 7 days of 

inundation (flooding or ponding) during the growing season in most years. 

The concept of hydric soils includes soils developed under sufficiently wet conditions to 

support the growth and regeneration of hydrophytic vegetation. Soils that are sufficiently 

wet because of artificial measures are included in the concept of hydric soils. Also, soils 

in which the hydrology has been artificially modified are hydric if the soil, in an unaltered 

state, was hydric. Some series, designated as hydric, have phases that are not hydric 

depending on water table, flooding, and ponding characteristics. As indicated above, like 

the NRCS, the Corps has typically accepted guidance for the identification of hydric soils 

developed by the National Technical Committee for Hydric Soils (NTCHS). The 

F-I.6-26
NTCHS, a working group organized by NRCS, has developed criteria for identifying and 

mapping hydric soils throughout the United States and defines a hydric soil as “a soil that 

formed under conditions of saturation, flooding or ponding long enough during the 

growing season to develop anaerobic conditions in the upper part [of the soil profile]” 

(http://soils.usda.gov/use/hydric/intro.html). The most recent (2000) version of the 

NTCHS hydric soils criteria identifies those soils that are likely to meet this definition. 

These criteria, which are accepted by most state and federal agencies, are as follows 

(http://soils.usda.gov/use/hydric/criteria.html):

1. All Histels except Folistels and Histosols except Folists, or

2. Soils in Aquic suborders, great groups, or subgroups, Albolls suborder, 

Historthels great group, Histoturbels great group, Andic, Vitrandic, and Pachic 

subgroups, or Cumulic subgroups that are: 

a. Somewhat poorly drained with a water table equal to 0.0 foot (ft) from 

the surface during the growing season, or 

b. poorly drained or very poorly drained and have either: 

(i.) water table equal to 0.0 ft during the growing season if textures 

are coarse sand, sand, or fine sand in all layers within 20 inches 

(in), or for other soils, 

(ii.) water table at less than or equal to 0.5 ft from the surface 

during the growing season if permeability is equal to or greater 

than 6.0 in/hour (h) in all layers within 20 in, or 

(iii.) water table at less than or equal to 1.0 ft from the surface 

during the growing season if permeability is less than 6.0 in/h 

in any layer within 20 in, or 

3. Soils that are frequently ponded for a long duration or a very long duration (7 

to 30 days) during the growing season, or 

4. Soils that are frequently flooded for a long duration or a very long duration (7 

to 30 days) during the growing season. 

On the basis of computer database searches for soils meeting the second criterion, NRCS 

has developed hydric soils lists for many parts of the country. Although they are useful 

for determining whether a particular soil series has the potential to support current hydric 

soil conditions

Field indicators of hydric soils are morphological properties known to be associated with 

soils that meet the definition of a hydric soil. Presence of one or more field indicators 

suggests that processes associated with hydric soil formation have taken place on the site 

being observed. The field indicators are essential for hydric soil identification because 

, caution should be used when using these lists for site-specific hydric soil 

determinations. Many soils on the lists have ranges in water table depths and other 

characteristics that allow them to be either hydric or nonhydric depending on landscape 

position and other site-specific factors (e.g., soil clay content, depth to bedrock). 

Accordingly, hydric soils lists are good ancillary tools to facilitate wetland 

determinations, but are not a substitute for onsite investigations. 

F-I.6-27
once formed, they persist in the soil during both wet and dry seasonal periods. However, 

few hydric soil indicators identify soils at a site as being currently hydric in accordance 

with the NTCHS hydric soils criteria described above. Field indicators of hydric soil 

conditions are listed in Table 4: 

Table 4. Field Indicators of Hydric Soil Conditions

(Based on 1987 Corps Manual and Corps Guidance Documents)

1. Indicators of Historical Hydric Soil 

Conditions: 2. Indicators of Current Hydric Soil Conditions:

a. Histosols

b. Histic epipedons;

c. Soil colors (e.g., gleyed or low-chroma colors, 

soils with bright mottles (Redoximorphic 

features) and/or depleted soil matrix 

d. High organic content in surface of sandy soils

e. Organic streaking in sandy soils 

f. Iron and manganese concretions 

g. Soil listed on county hydric soils list

a. Aquic or peraquic moisture regime (inundation 

and/or soil saturation for FRQWLQXRXVGD\V

b. Reducing soil conditions (inundation and/or soil 

saturation for FRQWLQXRXVGD\V

c. Sulfidic material (rotten egg smell)

The presence of one or more of the field indicators in “1 a, b, c, and/or d” above suggests 

that historical processes associated with hydric soil development have taken place at a 

given site. These indicators are useful in determining if soils at a site were historically 

formed under hydric soil conditions because the indicators persist in soils during both wet 

and dry periods and may remain for decades and even centuries after changes in site 

conditions occur that inhibit subsequent wetland development, such as the elimination of 

wetland hydrology (NRCS 1995). However, only the presence of field indicators “2 a, b, 

and/or c” confirms that hydric soils occur at a site during the period of observation. 

Hydric soil indicators have also been further defined and described in the Regional 

Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region 

(Version 2.0) (Corps 2008). These indicators are similar to those listed above from the 

1987 Corps Manual and are presented below in Table 5.

It should also be noted for problematic areas that the 2008 Corps Regional Supplement 

specifies 14 days continuous ponding as an acceptable indicator of problematic hydric 

soils (USACE 2008, p. 101). 

2.4.3 Prevalence of Wetland Vegetation

Species Classifications

Species classifications (e.g., tolerance of anaerobic soil conditions) are determined by 

consulting the National List of Plant Species that Occur in Wetlands (Reed 1988) and the 

relevant regional lists, which are published by FWS’ National Wetlands Inventory (NWI). 

Regional Interagency Review Panels develop the lists by determining species’ estimated 

probability of occurrence in wetlands vs. non-wetlands. Classifications are made by 

unanimous agreement of the Panel. If the Panel is unable to reach a unanimous decision 

on the status of a species, “no agreement” (NA) is recorded. If insufficient information 

exists to determine the status of a species, “no indicator” (NI) is recorded. Species that 

are not included in the NWI list are assigned a “not listed” (NL) designation in this report. 

The resulting NWI lists include plants that grow in a range of soil conditions from 

permanently wet to dry. Species are divided into the following “indicator categories”:

F-I.6-29
1. “Obligate wetland” (OBL) species, which, under natural conditions, occur 

almost always in wetlands (estimated probability >99 percent);

2. “Facultative wetland” (FACW) species, which usually occur in wetlands 

(estimated probability 67 – 99 percent), but are occasionally found in nonwetlands;

3. “Facultative” (FAC) species, which are equally likely to occur in wetlands 

or non-wetlands (estimated probability 34 – 66 percent);

4. “Facultative upland” (FACU) species, which sometimes occur in wetlands 

(estimated probability 1 – 33 percent), but more often occur in nonwetlands; and

5. “Obligate upland” (UPL) species, which occur in wetlands in other 

regions, but, under natural conditions, occur almost always in non-wetlands 

in the region specified (estimated probability >99 percent). 

Species that have an indicator status of OBL, FACW, and FAC are typically considered 

to be adapted for life in anaerobic soil conditions (Corps 1987) and are used as evidence 

of hydrophytic vegetation when they dominate plant community composition or cover. 

Despite widespread use of the lists for wetland delineations, it is important to note that 

wetland indicator species assignments are not based on the results of a statistical analysis 

of species occurrence. The indicator assignments are approximations of wetland affinity 

based on a synthesis of submitted review comments, published botanical literature, and 

the field experience of the members of the Interagency Review Panel. For this reason and 

because many plants have properties that enable them to occur in a range of microhabitats 

(i.e., wetlands and non-wetlands), the presence of wetland indicator species is not 

unequivocal evidence of the presence of wetland hydrology and hydric soils. A positive 

indicator or indicators of wetlands should be emphasized, such as an assemblage of plants 

that can only be considered “hydrophytes” when they are growing in water or partly 

drained hydric soils (not effectively drained hydric soils) (Corps 1987). From the FWS 

perspective, all species on the NWI plant lists are hydrophytes at one time or another and 

the wetland indicator status (OBL, FACW, FAC, or FACU) reflects the likelihood that a 

given individual of a species is a hydrophyte or a certain population of these plants is 

hydrophytic. While OBL and FACW species are the most reliable plant indicators of 

wetlands, FAC and FACU species also contain populations of hydrophytes (Tiner 2006). 

For the reasons stated above, the 1987 Corps Manual does not solely rely on the presence 

of hydrophytic vegetation to make wetland determinations. 

Hydrophytic Vegetation Definitions 

The Corps’ 1987 Manual states that the wetland vegetation conditions are met when the 

prevalent vegetation (i.e., more than 50 percent of vegetation cover or tree basal area) 

consists of macrophytes that are typically adapted to sites having wetland hydrologic and 

soil conditions (e.g., periodic or continuous inundation or soil saturation). Hydrophytic 

vegetation is defined as “plant life growing in water or on a substrate that is at least 

periodically deficient in oxygen as a result of excessive water content” (Cowardin et al.

F-I.6-30
1979). Hydrophytic vegetative species, due to morphological, physiological, and/or 

reproductive adaptation(s), have the ability to grow, effectively compete, reproduce, 

and/or persist in anaerobic soil conditions. Positive indicators of the presence of 

hydrophytic vegetation include: 

1. More than 50 percent of the dominant species are rated as Obligate ("OBL"), 

Facultative Wet ("FACW"), or Facultative ("FAC") on lists of plant species 

that occur in wetlands (see Reed 1988 for California); 

2. Visual observations of plant species growing in sites of prolonged inundation 

or soil saturation; and 

3. Reports in the technical literature indicating the prevalent vegetation is 

commonly found in saturated soils. 

Hydrophytic vegetation indicators have been further defined and described in the 

Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West 

Region (Version 2.0) (Corps 2008). These indicators include: 

1. Dominance Test

2.

. More than 50 percent of the dominant plant species across 

all strata are rated OBL, FACW, or FAC. 

Prevalence Index

3.

. The prevalence index is 3.0 or less with indicators of 

hydric soils and wetland hydrology being present. 

Morphological Adaptations. The plant community passes either the 

dominance test or the prevalence index after reconsideration of the indicator 

status of certain plant species that exhibit morphological adaptations for life in 

wetlands. 

F-I.6-31
3.0 DELINEATION METHOD

This study was conducted in accordance with Code of Federal Regulations (CFR) 

definitions of jurisdictional waters, the Corps’ 1987 Wetlands Delineation Manual, the 

Corps’ 2008 Regional Supplement to the Corps of Engineers Wetland Delineation 

Manual: Arid West Region (Version 2.0), A Field Guide to the Identification of the

Ordinary High Water Mark (OHWM) in the Arid West Region of the Western United 

States, A Delineation Manual, and supporting guidance documents. The following 

provides an overview of the objective of the delineation approach, how the Study Area is 

defined, and the methods used to identify and map (delineate) areas potentially subject to 

Corps jurisdiction under Section 404 of the CWA. 

3.1 Objective and Establishment of Study Area Boundary

The objective of this investigation is to identify and map areas potentially meeting the 

Clean Water Act definition of wetlands and Other Waters of the United States within the 

potential impact footprint of the DesertXpress Project. This impact footprint, which is 

encompassed within the Study Area, includes the proposed alignment and any alternative 

alignment and support facilities such as passenger stations and operations and 

maintenance facilities (e.g., maintenance yard, power substations, and transmission lines). 

 Temporary construction areas for equipment and materials laydown, new access roads, 

and borrow areas are also included within the Study Area. The boundary of the Study 

Area also represents a slightly larger area (increased alignment and facility ROW width 

by an average of 200 feet) to accommodate potential minor changes in the impact 

footprint. 

3.2 Study Area Reconnaissance

Prior to initiating detailed field survey work, existing land forms within the Study Area 

that may potentially contain wetlands or other waters of the United States were identified 

by conducting vehicle and pedestrian on-site reconnaissance inspections during the month 

of April 2010 in conjunction with review of the following information: 

x Aerial photography and satellite imagery of the area;

x USGS topographic mapping; 

x NRCS soils mapping; 

x Engineer scale topographic mapping of segment alternatives

x USGS National Hydrology Dataset; and

x Preliminary level vegetation mapping and wetland / OHWM data collection 

efforts conducted during February and March 2008 and September and October 

2009 as part of an on-going Federal EIS process by the FRA’s EIS contractor. 

The above efforts led to the development, in coordination with Corps regulatory staff, and 

use of the project-specific methods described below. 

3.3 Wetlands Identification and Delineation

Field surveys designed to identify the presence or absence of field indicators of wetland 

F-I.6-32
vegetation, soils and hydrology conditions were conducted within low-lying landscape 

features where wetlands could potentially occur. These field surveys were conducted 

during the months of April, May, and June 2010. 

3.3.1 Dominance of Wetland Vegetation

Presence or absence of a dominance of wetland vegetation / hydrophytes within the Study 

Area was evaluated using the methodology described in Sections 2.2 and 2.4.3. Indicator 

status of plants was confirmed by referring to the National List of Plant Species that 

Occur in Wetlands: 1988 National Summary (Reed). Plant cover data were collected for 

individual species associated within and immediately adjacent to the landscape features 

identified during the site reconnaissance survey as having the potential to meet the Corps’ 

technical criteria for wetlands. Plant cover was visually estimated within 3-foot diameter 

plots at each soil sample location and was recorded on a Corps Wetland Determination 

Data Form – Arid West Region. Copies of completed data forms are provided in Exhibit 

B2. Subsequently, field data were analyzed to assess whether 50 percent or greater of the 

dominant species within the area sampled are hydrophytes. Sites that are depressional 

landforms that do not have a dominance of wetland vegetation forming at least 5 percent 

cover were not considered to be dominated by hydrophytes and were classified as a 

potential “other water of the United States” following the methodology described in 

Section 3.4, below, except if conditions for problematic vegetation were met as described 

in the Corps’ 2008 Regional Supplement to the Corps of Engineers Wetland Delineation 

Manual: Arid West Region (Version 2.0).

3.3.2 Presence of Hydric Soil Indicators

The presence or absence of hydric soil field indicators was evaluated following the 

methodology described in Section 2.3.2 using the Regional Supplement to the Corps of 

Engineers Wetland Delineation Manual: Arid West Region (Corps 2008). At each 

potential wetland sampling location within the Study Area, hand-dug soil pits were 

excavated to a minimum of 20 inches or until a limiting layer or standing water is 

reached. The presence or absence of hydric soil indicators found at each soil pit location 

was recorded on a Corps Wetland Determination Data Form – Arid West Region. Copies 

of completed data forms are provided in Exhibit B2. For sampling locations where the 

possibility of problematic hydric soils is found, procedures for the identification of 

problematic hydric soils as defined by the above described publication were followed. 

3.3.3 Presence of Wetland Hydrology Indicators 

The presence or absence of wetland hydrology field indicators were assessed following 

the methodology described in Section 2.3.1 using the Regional Supplement to the Corps 

of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0) (Corps 

2008). The presence or absence of wetland hydrology indicators at each soil pit location 

was recorded on a Corps Wetland Determination Data Form – Arid West Region. Copies 

of completed data forms are provided in Exhibit B2. For sampling locations where the 

possibility of problematic hydrology indicators was found, procedures for the 

identification of problematic hydrology indicators, as defined by the above-described 

publication, were followed. 

F-I.6-33
3.4 Identification and Delineation of Other Waters

Field surveys designed to identify the presence or absence of field indicators of an 

ordinary high water mark (OHWM) were conducted within low-lying landscape features 

where other waters of the United States could potentially occur. These field surveys were 

conducted during the months of April, May, and June 2010 after the detailed 

methodology was reviewed and approved by Corps staff during May 2010. 

HBG identified drainages within each watershed that potentially met the Corps technical 

criteria for Other Waters of the United States (presence of field indicators of active 

surface water flow and associated Ordinary High Water Mark [OHWM]) using the 

following approach based on A Field Guide to the Identification of the Ordinary High 

Water Mark (OHWM) in the Arid West Region of the Western United States, A

Delineation Manual.

Initial efforts involved identification of all drainages within the Study Area having the 

potential for active surface flow. This was accomplished through field reconnaissance 

and imagery interpretation. Detailed sampling was then conducted to identify and 

delineated active drainages with an OHWM. This was accomplished by randomly 

sampling the identified drainages in a stratified manner by geographically dividing the 

Study Area into HUC 12 watershed units.

Field sampling within each HUC 12 watershed consisted of gathering OHWM data, 

including the measured width of the OHWM, for 3 to 5 main drainages (> 3 feet), if 

present, selected at random; and 6 to 10 (depending on watershed size) random samples 

of minor drainages (IHHWLISUHVHQW(DFKRIWKH+&&ZDWHUVKHGVORFDWHGZLWKLQ

the Study Area was divided into approximate thirds. Then a minimum of one major 

drainage and two minor drainages, if present, was sampled within each third of a 

watershed. Where the length of the watershed along the project alignment alternatives 

was less than 5 miles, the watershed was divided into approximate halves instead. If the 

minor drainages (IHHWRFFXUring within each one-third watershed varied in OHWM 

width by more than 33 percent, sampling was increased in that third of the watershed. 

Drainage data for each of the watershed drainages sampled were collected on a 

standardized field data sheet (Exhibit B2). Exhibit A, Figures 5-12 provide examples of 

the types of field indicators observed within various drainages along the DesertXpress 

Project alternative alignments. Each field sampling point was memorialized using a 

handheld GPS unit with submeter accuracy. Where stormwater flows originated upslope 

of the side of I-15 opposite the alignment, those drainages were hydrologically cut off by 

the freeway during construction and channeled into detention basins and / or manmade 

drainages on that side of I-15. As a consequence, drainages on the proposed alignment 

side of I-15 were hydrologically cut off from their sources and no longer technically meet 

the Corps OHWM criterion. This condition was noted on the field data sheets. Detailed 

OHWM indicator data for these historical drainage features were not collected. 

F-I.6-34
All drainage data (field and photointerpreted drainage data) are summarized by HUC 12 

watershed on the required Los Angeles District Excel JD Summary Data Sheet (see 

Exhibit B1). Widths for active drainages identified through photointerpretation are based 

on an average width calculated from field data. The length of each drainage is based on 

photointerpretation. Standardized field data sheets are provided in Exhibit B2. 

Representative photographs of various drainage features are presented in Exhibit A on 

Figures 13 – 33. The field data collected from each watershed were used to aid in the 

imagery interpretation process described in Section 3.5, below. 

3.5 Mapping

Wetland indicator data sample locations and the locations of areas identified during field 

surveys that are potentially Other Waters of the United States due to the presence of an 

OHWM were mapped using a hand-held Trimble XT global positioning system (GPS) 

unit with sub-meter accuracy. This GPS data was incorporated into a Geographic 

Information System (GIS) and geo-referenced in overlay fashion onto digital 

orthorectified satellite imagery and/or high resolution aerial photograph depending on 

availability. Overlays were used to assist in analysis, identification, and digitization of 

the location and geographic extent of areas that could potentially qualify as waters of the

United States. The imagery interpretation process involved the combined use of available 

imagery, field data, engineer level topographic mapping, field verification of mapped 

features and best professional judgment to map the geographic extent of areas potentially 

subject to Corps CWA jurisdiction. Exhibit C comprises detailed 1”=200’ scale mapping 

of the Study Area with field sampling points and delineated active linear drainage 

features. Labeling indicating their average OHWM width was overlain on orthorectified 

digital imagery. The maps are provided in digital PDF format due to the extensive 

numbers of maps required to show such detail. 

F-I.6-35
4.0 TECHNICAL FINDINGS

The following sections describe the landscape features and field indicators found within 

the Study Area that provide a technical basis for (a) determining the presence or absence 

of a potential water of the United States; and (b) defining the geographic extent of any 

potential water of the United States identified. Two types of landscape features were 

found that potentially contain waters of the United States. These include: 

1. Natural drainages

2. Manmade drainages

4.1 Field Indicators of Hydric Soils

Based on field observations within the Study Area soil indicators were not found that 

meet the hydric soils criteria defined by current Corps’ regulatory guidance, including the 

2008 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid 

West Region (Version 2.0). Onsite observations of surface conditions, including road and 

channel bank cuts, and interpretation of aerial photography revealed two primary soil 

types, desert pavement and more active wash sediments. Onsite examination revealed 

that soils or substrates within both natural drainages and manmade drainages consist of 

alluvial materials primarily made up of sorted sands and gravel, and are well drained, 

ranging from moderately well drained to excessively well drained.

4.2 Field Indicators of Wetland Hydrology Conditions

Based on field observations within the Study Area wetland hydrology indicators were not

found that meet the wetland hydrology criteria defined by current Corps’ regulatory 

guidance, including the 2008 Regional Supplement to the Corps of Engineers Wetland 

Delineation Manual: Arid West Region (Version 2.0). Onsite observations revealed 

evidence of flooding within the low-lying natural and manmade drainages. These 

observations also showed that there was no evidence of ponding and soil saturation for 

long to very long periods of time. The lack of ponding and soil saturation conditions 

meeting the wetland hydrology criteria is a direct result of the moderately well drained to 

excessively well drained alluvial soils. 

Although wetland hydrology conditions were not found within the Study Area, the field 

indicators of active surface water flow or flooding found within natural and manmade

drainages were sufficient enough to form Ordinary High Water Marks (OHWM). As 

indicated in Section 2.0, an OHWM provides a technical basis for (a) determining the 

presence a potential water of the United States; and (b) defining the geographic extent of 

potential water of the United States. 

The natural and manmade drainages within the Study Area found with an OHWM 

exhibited the following characteristics which are discussed in detail in the following 

subsections: 

F-I.6-36
1. identifiable field indicators of surface flow 

2. identifiable landscape features that supports surface flow

3. identifiable landscape features with a recognizable OHWM 

Exhibit A, Figures 5-12 provides typical examples of field indicators of active surface 

water flow and OHWMs found within ephemeral drainages occurring within the 

DesertXpress Project Study Area. Exhibit A, Figures 13-33 provide photographs of 

various types of drainages observed within the HUC 8 Mojave watershed. 

4.2.1 Field Indicators of Surface Flow

Review of topographic mapping (USGS and Engineer scale) and imagery of the Study 

Area provided visual indication of the presence of curvilinear depressional land surface 

features where focused surface water flow could potentially be directed. Linear drainage 

features associated with road drainage and flood control were also found. Field 

investigations confirmed the presence of surface flow within a number of these channels 

or drainages while others lacked evidence / field indicators of active ephemeral surface 

water flow. No drainages were found to contain evidence of perennial or intermittent 

surface water flow, and no evidence of subsurface flow was found in the form of spring 

discharges, artesian flows or indicia of a high groundwater table. Observation of active 

natural and manmade ephemeral drainages revealed evidence of surface water / 

hydrologic connectivity with other active drainages within and outside the Study Area. 

These ephemeral drainages are locally referred to as “desert dry washes.” The manmade 

drainages served to redirect surface flow from altered natural drainages. Indicators of 

drainages having active surface water flow paths included (1) water marks defined by 

linear deposits of fine-grained sediment, minerals and/or plant debris; (2) bank scour, 

erosion, and/or shelving; (3) deposits of sorted alluvial materials; and (4) flow-deposited 

woody and soft tissue plant debris (Exhibit B2). 

Flow-deposited woody and soft tissue plant debris were typically absent in drainages that 

did not have active surface flow. If woody debris was present, the pieces observed were 

relatively thick (i.e., greater that 1⁄4 inch) weathered limb or root material or milled posts 

or lumber. The wood pieces found were randomly placed and were not part of a 

collective flow line of deposited woody and/or soft tissue plant debris, which would be 

indicative of an active channel. The historical drainages were found to possess one or 

more of the same type of indicators found in active drainages, but the indicators found 

were considerably weathered. Surface flow indicators such as bank scour, erosion, and 

shelving areas had rounded edges in contrast to those found in active drainages having 

angular edges. Water marks defined by linear deposits of fine-grained sediment and 

minerals, and sorted alluvial materials such as gravels, cobbles and boulders were etched 

or varnished from weathering. The historical drainages were found to consist of the 

historical remains of channel drainages that were abandoned due to upslope changes in 

drainage due to either channel down-cutting or the channel becoming abandoned as the 

surface drainage became redirected or changed course due to deposition of alluvial 

material damming the channel flow path. The historical drainages were found to lack 

F-I.6-37
indicators of active flow. 

Surface water flow patterns were also found within various portions of the landscape that 

were relatively flat. These surface flow areas were defined by flow-deposited fine 

grained sediment or soft tissue plant debris. The visible surface flow pattern at these 

locations would continue for several feet then disappear either on a relatively flat soil 

surface or localized depression. 

Based on the above technical findings and as documented in Exhibits B and C, drainages 

were found with indicators of active surface water flows within the Study Area. 

4.2.2 Landscape Features that Support Surface Flow

Detailed field surveys identified land surface features that have the potential to convey 

surface flows. These features included a bed or channel and abutting banks. These 

physical features were found associated with both active flow areas and historical 

drainages. These drainage types can be summarized as follows:

1. Active drainage channel and abutting banks containing evidence of recent surface 

flows as indicated by the presence of unweathered sediment material (sand, 

gravel, cobbles, etc.) with unweathered surfaces, and the presence of flow 

deposited woody debris and/or soft tissue plant debris. 

2. Active drainage channel and abutting banks containing evidence of historical 

surface flows as indicated by the presence of unweathered sediment material 

(sand, gravel, cobbles, etc.) with unweathered surfaces, but lacked the presence of 

flow deposited woody debris and/or soft tissue plant debris. 

3. Historical drainage channels and abutting banks having no evidence of recent 

surface flow as indicated by weathered sedimentary gravel, cobbles, boulders, 

erosional or depositional deposits, and the lack of flow deposited woody debris 

and/ or soft tissue plant debris. 

The frequency interval of flow events within drainages with observable plant debris (1 

above) and unweathered sediment material is estimated to be within the 1 to 15 year 

range. Strojan, et al. (1987) found that surface litter decomposition rates for creosote 

bush and burro bush in the Mojave Desert were 42.5% and 58.4%, respectively over a 54-

week period of study. Kemp, et al. (2003) reported a similar one year decomposition rate 

for creosote bush and a 74% loss within a 41-month period. This lends support to 

qualitative observations made by one of the preparers of this report, Dr. Terry Huffman, 

who has observed over 20 + years of delineating wetlands within arid environments that 

soft plant tissue (i.e., pieces of plant leaves and thin bark) will decompose in arid 

drainage environments within a 2 to 3 year period. In addition, field observations over 

these years indicated that small woody stems (<1/4 inch) decompose over many more 

years, perhaps 10 + years. For older drainages where the surfaces of the sediment 

material (e.g., sand, gravel, cobbles, etc.) is no longer smoothed by the interaction of 

surface water flow and transport, but weathered, and lacks flow deposited woody and thin

channels to prehistoric times for deeply incised channels (i.e. > 6 feet in desert pavement 

areas).

The land surface of the Study Area is characterized by the presence of active and inactive 

alluvial fan systems. Ephemeral drainage channels are found on both types of these 

alluvial fan types. The majority of the ephemeral channels supporting active surface 

water flow were narrow, with an average width of less than 3 feet. Active alluvial fans 

were characterized by sandy soils, a uniform vegetation type, and evidence by surface 

flow patterns indicative of surface water sheetflow. Narrow channels within these areas 

were both weakly expressed and discontinuous. This discontinuity indicated that new 

channels could be formed with each major flood event resulting in the current channels 

being bypassed and blocked off. Channels >3 feet wide were also found. These channels 

were considerably deeper that the narrow channels found and were less common when 

considering the landscape as a whole in relationship to the Study Area. Evidence was 

found within both of these channel types where previously bypassed cutoff channels 

where becoming filled with sediment. The specific conditions varied within the Study 

Area.

Based on the above technical findings, drainages with active surface flow were found 

within the Study Area with physical features that allow for the conveyance of surface 

flows. 

4.2.3 Landscape Features with a Recognizable OHWM

The desert dry washes with active flow were found to have identifiable features which 

represented the geographic reach of lateral surface water. These features included 

channels or beds with evidence of active flow and abutting banks which demarcated the 

lateral reach or extent of flow. Field indicators of the extent of active flow along the 

banks included water marks defined by linear deposits of fine grained sediment and/or 

minerals, bank scour, erosion, and/or shelving, and flow deposited woody and soft tissue 

plant debris (Exhibit B2). 

Based on the above technical findings, the active drainages, described in the above 

subsections, have recognizable landscape features from which the lateral extent of surface 

water flow can be geographically delineated. Field indicators of this surface water flow 

were used to identify the OHWM. The maps in Exhibit C show the locations of these 

active ephemeral drainages.

4.3 Field Indicators of Wetland Vegetation

On the basis of field observations within the Study Area, a dominance of wetland plant 

species or hydrophytes was not found. Based on this result, the criteria defined by current 

Corps’ regulatory guidance, including the 2008 Regional Supplement to the Corps of 

Engineers Wetland Delineation Manual: Arid West Region (Version 2.0) for wetland 

vegetation were not met.

F-I.6-39
4.4. Presence of Wetland Vegetation within Natural and Manmade 

Drainages

Based on field observations within the Study Area a dominance of wetland plant species 

or hydrophytes was not found within natural or manmade drainages within the Study Area 

where active ephemeral drainages were found.

F-I.6-40
5.0 AREAS POTENTIALLY SUBJECT TO JURISDICTION 

This section presents the findings of this delineation with respect to the identification and 

geographic extent of areas found that could potentially be regulated by the Corps and the 

EPA as wetlands or other waters of the United States under Section 404 of the Clean 

Water Act.

5.1 Wetlands 

No areas meeting the Corps technical criteria for wetlands were identified within the 

Study Area. These findings are based on the absence of hydric soil, wetland hydrology, 

and / or wetland vegetation indicators as required by the Corps’ 1987 Manual, the Arid 

West Regional Supplement, guidance documents, and regulations. 

5.2 Other Waters of the U.S.

Ephemeral drainages or desert dry washes were found within the Study Area that meet the 

technical criteria to potentially be subject to CWA Section 404 jurisdiction as Other 

Waters of the United States (Exhibit C). This finding is based on the presence of an 

OHWM as required by Corps regulations. Length and width measurements of the 

ephemeral drainages found to contain an observable OHWM are provided in Exhibit B1.
